Double-stranded polynucleotide activates the expression of immune recognition molecules. The polynucleotide can have a minimal length and activates the expression of molecules not encoded by a nucleotide sequence that is not necessarily related to the polynucleotide. The present invention provides for a simple and specific system to activate expression of Class I and/or Class II molecules of the major histocompatibility complex (MHC), and allows regulation of expression of MHC molecules on the cell-surface of antigen presenting cells and other immune cells. Also provided are systems for the screening, identification, and isolation of compounds that increase or decrease this activation.
双链多核苷酸可激活免疫识别分子的表达。多核苷酸可以具有最小长度,并能激活与多核苷酸不一定相关的核苷酸序列未编码的分子的表达。本发明提供了一种激活主要组织相容性复合体(
MHC)I 类和/或 II 类分子表达的简单而特异的系统,可以调节抗原呈递细胞和其他免疫细胞细胞表面
MHC 分子的表达。此外,还提供了用于筛选、鉴定和分离增加或减少这种激活的化合物的系统。
